What is the Chain of Survival?

How would you react if you saw someone going into cardiac arrest? Most people freeze and hope that the casualty is okay while their survival rate decreases around 9% each minute that was no action taken. The chain of survival is a series of action's that, when properly executed, can reduce the mortality associated with sudden cardiac arrest.

In this blog, we define and explain each step in the chain of survival.

Early call for help

The first step is to recognise that a cardiac arrest is occurring. Most casualties feel very ill before the heart stops beating (cardiac arrest).

An early call for help might prevent cardiac arrest in the first place. If the casualty is unconscious and not breathing, call an ambulance immediately to ensure defibrillation and life support arrive as soon as possible.

Unfortunately, during a crisis, some people will question the need for an ambulance and instead phone friends or family. Those lost minutes could mean the difference between life and death in a cardiac attack.

Early CPR

In cardiac arrest, (CPR) is urgently needed to get oxygen to the heart and brain to prevent cell death. If (CPR) starts within 4 minutes of the heart-stopping and oxygenation of vital organs like the brain can be maintained.

With a ratio of 30 chest compressions to 2 breaths, CPR helps to move blood and oxygen around the body until an automated external defibrillator (AED) arrives, and help comes.

Early defibrillation

The best chance of restarting a heart is with a ‘defibrillator’. If (CPR) is given within 4 minutes and defibrillation within 8-12 minutes, there is a significant improvement in survival rate.

Each minute without defibrillation reduces the chances of survival by 9%. Anyone can use a defibrillator as they provide audio instructions in the steps to follow.

Post resuscitation care

Medical treatment such as giving medication and stabilising the airway will increase the chance of survival even further and help restore the quality of life.

The casualty will need to visit a hospital for appropriate care and monitoring to ensure their long term health and wellbeing.
